Abstract (en)
[origin: WO2006059951A1] An LC resonator (117; 122) for a voltage controlled oscillator (13; 116) comprises an inductive transmission line 31; 51), and input and output ports (33a-b; 53a-b) connected to the transmission line, wherein the transmission line is grounded (G) in at least one end portion thereof. The inductive transmission line comprises a plurality of connection ports (P) that are capable of being connected to each other or to ground in order to tune the resonance frequency of the LC resonator from one frequency band to another. Further, a trimming capacitor (C) may be interconnected in the transmission line in order to further tune the resonance frequency of the LC resonator. Preferably, the LC resonator is formed as a microstrip or strip line structure in essentially a C or S shape on a laminate substrate (101-103).
